Time Sync Issues Exacq And Hikvision Cameras

Undisclosed Integrator #1

I have been fighting this issue for a few days now with no avail. I have Hikvision DS-2CD4112FWD cameras that seem to drift in time over a period of a day. Once i connect the cameras in the exacq VMS and review the video they are perfectly sync'ed up, then after about 12 hours they are off by 2-5 seconds. I have configured the exacq vision to be the time server, i don't have an alternate NTP server configured, the camera shows the NVR as the time server. I have modified the NTP update field in the cameras to update every hour, and they are still off. i found a windows task to sync the time, and set that to hourly with out any success. cameras are on a flat network on my testing bench.

Does any one have any suggestions or had any advice on this one? I have never had issues with cameras drifting this much in the past. Cameras are on the latest firmware, exacq is on the latest release.
